基于网络传输的实时图像融合系统设计

Real-time image fusion system based on net transmission

  • 摘要: 为了实现图像融合系统远距离实时传输,提出一种基于TI公司TMS320DM642和TMS320DM365处理器平台的高速网络传输图像融合系统的设计方案。设计基于TMS320DM642融合模块和基于TMS320DM365网络传输模块,解决了图像融合模块和网络传输模块间的数据通信问题;在融合模块中实现图像配准和图像实时融合,融合图像数据在网络传输模块中进行H-264算法压缩并根据RTP(real-time transport protocol,实时传输协议)协议实现RTP封包处理,传输码率约为460 kb/s;利用线程间管道通信技术,实现了一种新的基于RTP/RTSP(real time streaming protocol,实时流传输协议)嵌入式流媒体服务器的搭建方法。实验结果表明:系统总体图像延迟为300 ms左右。

     

    Abstract: In order to achieve the long-distance real-time transmission of image fusion system, a high-speed network transmission image fusion system design scheme based on TI TMS320DM642 and TMS320DM365 processors was presented. Fusion module based on TMS320DM642 and net transmission module based on TMS320DM365 were designed, and the data communication problem between the image fusion module and net transmission module was solved. Image registration and real-time image fusion were achieved in fusion module. Image data was compressed by H.264 algorithm and carried out real-time transport protocol (RTP) packet processing according to RTP protocol in net transmission module, and the transmission rate was about 460 kb/s. Using thread pipe communication technology, a new establishment method based on RTP/real time streaming protocol (RTSP) embedded streaming media server was achieved. Experimental results show that the overall system image delay is about 300 ms.
